Refill your prescription while you still have a 5- to 7-day supply left. Some sources, such as mail order pharmacies, have a longer lead-time for refills. Also, use one pharmacy if possible.
Keep your medications in their original containers in your carry-on luggage when you travel. Do not pack your medications in checked luggage in case your suitcase is lost. Take extra medication with you when you travel in case your flight is delayed and you need to stay away longer than planned.
